METHOD OF ORNAMENTING SURFACES.

SPECIFICATION forming part of Letters Patent No. 708,498, datedSeptember 2, 1902.

Application filed February 16, 1901.

To all whom it may concern.-

Be it known that I, J OHANNES PAUL RU- DOLPH, a subject of the GermanEmperor, residing at 32 Mittelstrasse, Gorlitz, in theKingdom of Prussiaand Empire of Germany, have invented a new and useful Method ofOrnamenting Surfaces, of which the following is a specification.

My invention relates to a method of ornamenting surfaces, and has forits object to obviate the running or confusion of the colors or mordantsapplied to such surface. This method, which is designed to be used forwood and like materials where the colors are liable to run, consists insubdividing the surface by inlaid metal strips into separate areas andapplying liquid colors to these areas.

In the accompanying drawing I have represented by way of example a pieceof wood with an inlaid metal strip in section to a greatly enlargedscale to show how my said invention may be carried into effect.

The metal strip A, inserted into the wood B, consists of flat wirehaving a sharp edge Ct, the flanks converging from b 1) near the middleor at any desired point of the lower or upper part. In order to retainthe wire in the groove serving for its reception, its flanks arefurnished with ribs 0, which after the manner of barbed hooks form assharp corners as possible, so that they may penetrate into the sides ofthe groove and prevent the loosening of the wire. The number and size ofthe ribs may be varied at will, according to circumstances.

As compared with the method set forth in the English specification No.11,449, A. D. 1889, where the running of different colors $8Ii'rt 747,691. (No specimens.)

applied to adjacent areas is to be prevented by providing groovesbetween the areas, my

aforesaid method has the advantage that a thicker layer of the coloringliquid may be applied to the several areas without interfering with theadjacent parts, which is of great importance, particularly in the caseof mordants. Thisadvantageisgainedbytheliquid having a greater tendencyto reduce its free surface to a minimum in the case of areas confined bymetal than of areas confined by grooves. With the method described inthe English specification No. 11,449, A. D. 1889, the mordant, when asomewhat thick layer be applied, runs into the grooves, therebyaffecting the adjacent areas. In addition to this result the separationof areas by inlaid metal strips as compared with the separation bysimple grooves has the advantage that the several parts are preventedfrom bending or warping, which is very useful, more especially fornarrow spaces representing stalks, narrow leaves, and the like.

What I claim as my invention, and desire to secure by Letters Patent,is-

The method of ornamenting surfaces, which consists in subdividing thesurface into separate areas by inlaid metal strips, and then applyingliguid colors to the separated areas, substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
